Nice books all Frisco, but what a nice upgrade on this one. Lots of Japanese War time covers (for obvious reasons), but not that many Chinese ones i can think of though.
Thanks Sagii, I'll upgrade when I can, evidenced by the two Super Mystery issues below, first my under copy, then my upgrade. It's crazy to think with how rare some of these books are that I've actually upgraded a few issues Oh and yes, I don't off hand recall any Chinese covers (without looking at the photo journals). These Ace books are quite cool
